Navdata at OPRN?

This Pakistani airbase has flown by some of foreign airlines. But how did they get the data? And Navigraph doesn’t have this airport. If able, please add it.

Hi,
OPIS replaced OPRN - OPRN is closed and will not be used for civil aviation any longer. Possible that the military still uses it, but that´s another data source and therefore not included in our source.

Cheers,
Richard
